You can't judge potential off of a singular statistic. Viciedo was consistently overmatched at the plate. Those 25 homers were a very small portion of his at bats. If a guy has zero chance in 350+ at bats out of 500 or so, you can't seriously think a professional scout is going to point at 25 singular instances and say "hey, this guy's gonna be something". That's not the way it works.

Except that people are providing evidence to the contrary, you can pretend that "no one but the Sox saw any potential in Viciedo" all you want, but it's basically been disproven at this point in this thread.
